Bug Description

Topo
====
nodek8 and nodek9 - compute
nodei30 and nodek10 - controller

Steps
=====
1]. Enabled VxLAN routing in the project.
2]. Configured the Encapsulation Priority Order as :
VxLAN
MPLS Over UDP
MPLS Over GRE
3]. Created 2 VNs and 3 VMs in each.
4]. Intra-VN ping from nodek8(10.1.1.4) to nodek9(10.1.1.3) goes thru fine.

5]. Inter-VN ping between nodek8(10.1.1.4) --> nodek9(20.1.1.3), however fails with the 'Discards' counter incrementing.

As per Manish (on his last day) this is probably a QFX issue that fixed the problem. There is no commit from contrail code. Since the bug is not seen anymore as per Ganesh from test team moving it to Invalid.
